PAPER BOX AND BLANK THEREFOR.

Specification of Letters Patent.

Patented Apr. 21,191 4.

Application led October 28, 1910. Serial No. 589,606.

To all 'whom it may concern Be it known that I, ELIE W. LABOMBARDE, of Nashua, in the county of Hillsboro and State of New Hampshire, have invented cer- Boxes and Blanks Therefor, of which the following is a specification.

One of the chief items of the 06st of making paper articles of the type commonly knownas ice cream boxes, is the labor of aflixing the handles by which said boxes are carried, this aflixing being done by hand. The handles consist of flexible strips, and are commonly called the tapes In another application filed by me on Oct. 28, 1910, Serial No. 589,607 ,I have disclosed and claimed a machine for automatically affxing the tapes to the blanks, which machine performs the work at the rate of several thousand an hour. Said machine employs curved fingers which t-uck or insert the ends ofthe tape through apertures in the blank, and

aliix said tape ends to portions of the blank adJacent the apertures which have had small areas or spots of an adhesive applied 4thereto by other parts of the machine. For practical reasons it is essential that the apertures be made in certain portions of the blank, and it is also essential that the apertures shall permit the fingers of the machine to pass through, and that, aft-e1' the fingers have performed their functions, the apertures shall substantially cease to exist. f One of the objects of the present invention is to provide blanks capable of having the tapes automatically affixed thereto without. interfering in the least with the carrying qualities of the boxes or pails when the blanks are folded for use.

Another object is to provide a box or pail having a tape handle secured to two sides thereof by an adhesive in such location and in such a manner, that the contents cannot come in contact with the adhesive, or with the tape, or escape through the apertures for the tape. A

To these ends the invention therefore consists .in the blank, and in the b'ox or pail foldedup from such blank, substantially-as, hereinafter described and claimed. i

0f the accompanying drawings: Eigure 1 is a plan view of the blank. Fig. 2 isa perspective view of the same folded up to form a box or pail. Fig. 3 represents a section on line 3-3 of Fig. 2, on a larger scale.

Similar reference characters designate the same parts in all of the views.

A sheet of stock of the kind of paper usually employed for the purpose is cut and scored or creased to form sections and wings and flaps which can best be described by reference to the posit-ions which'they `oc cupy when the blank is folded up to box form. The longitudinal middle portionof the blank is continuous from end to end and comprises the bottom 5, two sides 6,A 7, an end flap 8 having a slit 9, and another end flapv 10 having a tongue 11. From the four corners of the. bottomsection 5, four cuts 12 extend to the side edges of the blank to form two wings 13 of the section 6 and two wings 14 of the section 7. The material between the cuts 12 is left so as to form wings 15 that are folded up between the wings 13, 14. Projecting from the ends of wings 14 the Haps 16 which. when the box is filled I and closed, are folded under the flapsy 8 and 10 and with the latter constitute the top of the box. Thetongue 11 is slipped into the slit 9 to hold the top closed.

As so far described, the box is of a well known type, usuallycalled an ice cream box, or pail, and it has a bottom and 'two sides of single thickness, the other'two sides being partly double and partly trlple thick, the latter being due to the wings 15' which usually lie between the wings 13, 14. Such boxes are commonly provided with tape handles or bails. y ,n

In carrying out my inventlon, I provide each of the wings 14 with a U-shaped slit to form a tongue 17. extending toward the cuts the wing 14 from the flap 16. Thistongue yields when the inserting finger of the machine carries the end of the tape through the aperture resulting from deflection of the tongue, so that the end of the tape can 'be pressed down by thetip of said finger on a spot of adhesive a placed on the blank ne thebottom of the U-shaped slit. In Fig.

the tape is indicated only by .the dotted lines, in order to permit illustration of the spots@ of glue or other adhesive. yAfter the tape ends have been affixed, the tongues v17 return to place so as to lill` up the temporary apertures, the presence of the tape preventing said tongues frombeing deflected beyond. proper plane. When thekblank is folded up to constitute a box or pail as unslitted inner Wings 13 as sliownvin Fig. 3,

so that thecontents of the box can never come in Contact withany of these portions. When the boxI is lled, and being carried by .its tape handle or bail, the tongues can never get out of position because they are confined by the taut portions of tapey extending over their outer faces, against the internal pressure of the contents holding the wings 13 against the inner walls of the wings 15.-

VVhile I have referred to the member Z) as a tape it is to be understood that I do not limit myself to a strip of flat fabric, as any material capable of the same utility may be employed.

Asbest shown in Fig. 3, the box when made up is )capable of carrying liquid contents such as ice cream not lonly Without danger of the said contents getting access to the tongues or the tape or the adhesive, but also the l'use of adhesive betweenl the contacting faces of the wings or sections 13, 14 retains the parts in such relative positions that the edges of the tongues are caused to bite or tightly grip the portions of the tape which passes down over the outer surfaces of the tongues and through the slits. Since said slits and the biting edges of the tongues are below the upper margins of the wings, the Weight of the contents of the box when filled andthe box is being carried causes the ten sion -on the tape to hold the tongues in against the support afforded by the -inner Wings. At the same time the upper margins of both wings add to the lateral support provided by the top flaps 8 and 10 (Fig. 2) to prevent the top of the box from being laterally collapsed by the inward pressure of the portions of the tape Which bear against the-outer faces of the tongue. Said tape therefore serves as a carrying handle A(not merely a tying device), which handle has its ends not only securely. held by the biting action of the tongues and also the adhesive,

vbut said adhesive is also shielded byl the inner side wings, as shown in Fig. 3, and the top or upperportion of the box is strengthened so as not to be collapsed by the inward pressure of the tape handle when the filled box is bein carried.

The location of the slits and tongues in the outer members of the overlapping side Wings, and the location of the tape ends passed through the slits, as shown in Fig. 3, results in having the tape ends and the tapelocking tongues in such position that when the contacting faces of the said overlapping Wings are glued or cemented together as is customary with this type of box, such gluing together prevents any liability of unlocking the tongues from their tape-biting positions.

I claim- A box having two of its sides composed of overlapping` sections, the outer sections having slits and tongues below their upper margins, and a tape extending over the top of the box and over the outer surfaces of the upper portions of the sides and through the slits and having its ends secured to the inner surface of the outer sections and protected by the inner sections, the inner sections being uncut or. continuous, whereby the contents of the box cannot reach the tongues or tape ends, the overlapping side sections being adhesively connected to hold the parts 1n position to cause the edges of the tongues to bite the tape.

In testimony whereof I have aliiXed-my signature, in presence of two witnesses.
